For more than 40 years, ICE SAS has been developing and producing  protection relays and systems dedicated to the railway sector.

We provide to our customers, such as SNCF Réseau, EUROTUNNEL, STIB, ONCF, KORAIL or AURIZON, a complete range of digital multifunctional protections for AC and DC railway applications, associated with complementary services.

ICE SAS equips railway substations all over the world with reliable and selective protection relays, in particular our best-selling PDZIN1 catenary protection dedicated to traditional or high-speed lines.

Always listening to our customers, we have developed our new 9000 Series of protection relays with advanced features simplifying the control and monitoring of any railway network. Based on a flexible architecture, our 9000 range can easily evolve to meet all your expectations.

ICE SAS operates and supports its customers in France and abroad through its sister companies and its network of agents.
